Re: Color Variations HELP?
It could also depend on what strain of rainbow is being stocked. those fish could be a different strain of rainbow. If I were to guess, the silver one is an adult stocker and the more colorful one has been in the system for a year or more. I have worked in trout hatcheries, and I have caught fish late in the summer that I stocked earlier in the summer. Fins and colors start to come back as the fish is in it's natural environment and when they start feeding on bugs and such as opposed to pellets.
